Hi All,

Is somebody looking into this?
I think this is correlated with the discussion "Are there any plans to develop Graphx Streaming?".

Using union / subtract on VertexRDD or EdgeRDD leads on the creation of new RDD but NOT in the modification of the RDD in the graph.
Is creating a new graph the only way to go to add /remove vertex or edge?

Hi Matei,

Could you please clarify why i must call union before creating the graph?

What's the behavior if i call union / subtract after the creation?
Is the added /removed vertexes been processed?

For example if i'm implementing an iterative algorithm and at the 5th step i
need to add some vertex / edge, can i call union / subtract on the
VertexRDD, EdgeRDD and Triplets?
